VALVE-SPRIN BEMOVER.

Application filed septernbenl, 1925.

The object of my invention is to provide a valve spring rem-over of simple, durable and inexpensive construction, which may be easily and quickly attached or removed from 5 a bench.

A further object is to provide a valve spring remover which is particularly adapted to be used in connection with removing springs from the stems of valves 10 commonly known as the overhead type. The

device is adapted to first compress the spring to permit the removal of the retaining pin and then to automatically remove the spring from the stem.

A further object is to provide a spring remover which may be mounted on a bench in a detachable manner and provided with means for compressing the valve spring by means of a foot lever so that the operator may have both hands free to properly manipulate the parts.

My invention consists in the construction, arrangement and combination or the various parts of the device. whereby the objects contemplated are attained. as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is an end elevation of my improved valve spring remover showing the manner in which it is mounted on a work bench.

Figure 2 is a side elevation of the same.

Figure 3 is an end elevation of the upper end of my valve spring remover showing the manner in which it is applied to a valve spring and the manner in which the same is compressed for removing the retaining pin.

Figure 4 is a view similar to Figure 3 showing the valve spring being removed.

Figure 5 is a detail sectional view taken on the line 5-5 of Figure 2; and

Figure 6 is a detail sectional view taken of the line 66 of Figure 1.

lscly improved device comprises a body portion 10 formed preferably of fiat bars of structural steel. The lower end of the member 10 is bent inwardly at 11. The portion 1.1 terminates in a downwardly extending portion 12. The upper end of the member 10 is bent inwardly at 13 which terminates in an inwardly and outwardly extending brace portion 14. Secured to the brace portion 14: is a member 15, the lower end of which is provided with a downwardly ex- Serial No. 56,232.

tending tongue 16. The tongue 16 is designed to be mounted in a bracket 17, said bracket being mounted permanently to the bench leg 18 by means of suitable bolts or rivets 19. The bracket 17 is provided with a vertical row of openings 20. V

Secured to the body portion 10 is one end of a latch spring 21, the upper end of which is provided with a pin 22 designed to be slidably received in an opeing 2.3 in the member 10 and in an opening 24 in the tongue 16. The said pin 22 is designed to be placed in one of the openings 20 and to thereby provide means whereby the support 15 may be adjusted vertically. This pin 22 also serves to lock the device in working position. It will be seen that the device may be easily and quickly detached by simply pulling the pin outwardly by means of the knob 25, after which the body portion 10 will be lifted upwardly and the tongue 16 caused to disengage the bracket 17. The member 12 and the tongue 16 are designed to rest against the leg 18 when in position as shown in Figure l. I

The upper end 01 the member 15 is provided with a pivoted lever 26, the free end of which is provided with a notch 27. The said notch is designed to receive the valve stem 28 when in certain positions of its movement.

Pivotally connected to the member 12 is a foot lever 29 which is provided with an opening 29 in one of which is pivotally connected a vertical rod 30, the upper end of which terminates in loop 31 designed to re ceive the members 14 and 15. The upper end of the loop portion 31 is pivotally mounted in one of the openings 26 in the lever 26. The lever '29 is normally supported in an elevated position by means of a spring 32. The lever 26 is also supported in an elevated inclined position as shown in Figure 1.

hen it is desired to operate the device. the tongue 16 is placed in position in the bracket 17 and secured therein by means of the pin 22. The lever 26 is extended over the top of the bench, after which thelever 29 is moved downwardly, causing the lever 26 to assume a substantially horizontal position, as shown by dotted lines. The valve head 33 is then grasped and the said head moved toward the free end of the lever 26 so that the stem 28 is in alinement with the notch 27. The free end of said lever 26 is may then be removed, after which body portion caused to enter between the coils of the spring as the said head is moved out-v wardly. The levers and 29 are then forced downwardly, which will cause the spring 3 1; to be compressed in the manner illustrated in Figure 3. The retaining pin levers and 29 are permitted to move up dly by the action of the spri which will ca se the spring to be removed from said valve stem in the manner clearly illustrated in Figure 4:.

Due 'to the fact that the valve heads of various makes are of dill'erent heights it is necessary to adjust the elevation of the lever 26, which is easily and quickly accomplished by pulling the pin 22 outwardly, which will permit the tongue 16 and the to be elevated or lowered the proper distance, and then the pin 22 may be permitted to move to a closed position and in another one of the openings 20.

Thus it will be seen that I have provided a valve spring remover of simple, durable and inexpensive construction which may be easily and quickly attached to a bench when desired to be used and when not in use ma be easily and quickly removed so it will not be in the way. It will be "further seen that I have provided a valve spring remover which may be actuated by the operators foot and thereby permit free use of the operi the retaining pin ators hands for removing and moving the valve head into position.

By providing the opening 26 in the lever 26 and the opening 29 in the lever 29 I have provided means whereby the leverage between said levers may be varied to operate on springs of different tensions.

I claim as my invention:

1. A valve spring remover comprising a vertical body member, means for detachably securing said body member to one side of a bench, the lower end of said body member terminating near the floor line and. its upper end terminating above the top of a bench, a valve actuating lever pivotally connected to the upper end of said supporting member, a toot lever pivoted to the lower end of said body member, and means for connecting said foot lever and said valve lever so that when the foot lever is moved downwardly the tree end of said valve lever will be moved downwardly over the top of the bench.

2.
